Hint: Follow the leader exit:
When your park is thriving, put up a "no entry" banner in front of the exit. A vast amount of guests who want to leave will not be able to, and will hang around by the exit. Note: Your park rating will drop. When you remove the banner, the crowd will stream out like lemmings.

Hint: Mow the grass:
Go to the "Raise/Lower Land" icon and click on the piece of land that you want mowed.

the most common is a keylogger called HotKeysHook or the file
has been packed/protected with VMProtect or Themida and
is recognized as Win32/Packed.VMProtect or Win32/Packed.Themida.
In ALL cases this is a FALSE ALARM as NONE
